From your description, we find the issue is related to Hyper-v, I would remove the tag of "msc-virtual-machine-manager-hyper-v", which represents deploying Hyper-v in SCVMM. Thanks!

Me too.
Hyper V has gone.
Virtual HDs (in C:\Users\Public\Documents\Hyper-V\Virtual hard disks) has gone.

Looking the timestamp, the changes occurred in 13/06/21, 10 days ago.

I hate this awful translate from Microsoft in this support pages.

I lost it all.
Great, Microsoft.

Hi,

What is the upgrade of the Windows 10, Windows 10 1709 or others?

After research, I found there are some similar cases that VMs disappear after upgrading to Windows 10 1709.

It seems you have found the workaround to fix the issue, if you would like to find the root cause of the issue, I would suggest you open a case with MS for deep troubleshooting:

Thanks for your time!
